get terminal width and height
I was reading Advanced Programming in the Unix Environment and it says to use ioctl() to get the terminal's width and height. I wrote this program:

Code:
// print width and height

#include <stdio.h>
#include <unistd.h>
#include <sys/ioctl.h>
#include <termios.h>

int main( int argc, char **argv ){
	struct winsize size;
	ioctl( 0, TIOCSWINSZ, (char *) &size );
	printf( "Rows: %u\nCols: %u\n", size.ws_row, size.ws_col );
	return 0;
}

When I ran it, the numbers it outputted were in the thousands, and when I started Vim up again, the terminal got overloaded. Everything turned into static and the activity monitor showed Vim occupying 1 GB of memory. Is there a way to get the right terminal dimensions and avoid this problem?
